An important broadcast is transmitted from Goiot, concerning security concern on escape hatches on many Catamaran brands, including Nautitech :

It is strongly advised to apply to Nautitech after sales services, to check if your cat is concerned and must have an appropriate repair.
Be sure that, if you don't react quickly, your insurance company is aware of the situation and will promptly consider that your coverage is no longer valid in case of flooding and sinking related with this disorder.
